Check if your proxy is down. You're using only Tor, so make sure you can still connect to that. If you can, check if you have any peers - maybe there are no Tor v3 peers for your node, although I would be baffled if that is indeed the case.
Probably not related to the issue but you have a typo in your config:
# Needed for full validation
addumevalid=0
-snip- 2023-02-09T02:34:22Z Ignoring unknown configuration value addumevalid
Should be assumevalid=0
Which resulted in skipped signatures verification of blocks older than height 751565.
The assumevalid block is a moving target that is changed during releases, so it is not guaranteed to stay at this block for the next version of Bitcoin.
